AUTOMATIC SLITTER TOOLING
AMAG has installed a new tooling robot on its slitting line, moving the company another step towards Industry 4.0, and improving efficiency and quality when cutting aluminium coils.
At the beginning of this year, a fully automatic tooling robot (ATR) was commissioned on the slitting line in use since 2012; the robot tools the slitting line with the required slitters.
A slitter essentially consists of a metal frame into which two knife arbors have been installed. A knife arbor consists of the circular cutting knives, the stripper rings (steel rings with rubber surfaces) and the spacer rings, which are available at intervals of 2 hundredths of a millimeter.
This ensures that the stringent customer requirements for width tolerances can be met. The ATR is used to assemble this complex system, benefitting from the automation to avoid assembly errors such as insufficient clearance.
After use, the slitter is dismantled and the individual parts taken to the tool store. The ATR takes the cutting knives to outward transfer stations, where the slitter expert checks the knives in order to ensure cut quality remains even. The knives are checked for sharpness, ruptures and burrs (when aluminium builds up on the cutter); any damaged or worn knives are set aside, and the remainder are returned to the knife store.
